I FIBE-EXTINGUISHER.

Application fiied November 7, 1911.

To all 1.071 am it may concern:

Be it known that I, HOWARD R. PARKER, a

citizen of the United States, residing at Athens, in the county of Henderson and State of Texas, have invented new and useful Improvements in Fire-Extinguishers, of which the following is a specification.

My invention relates to the class of fire extinguishers.

An object of my invention is to provide a simple and inexpensive fire extinguisher wherein are embodied means whereby the carbon dioxid gas may be formed when the same is inverted. 1

Another object of my invention is to provide av fire extinguisher which is constructed mostly of sheet metal, a glass tube being mounted therein, thereby obviating all the necessary parts which have heretofore existed in connection with fire extinguishers.

With the foregoing and other objects in view my invention relates to such details of construction and in the arrangement and combination of parts as will be hereinafter fully described and specifically pointed out in the appended claims.

In describing my invention in detail reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views and in which,

Figure 1 is a side elevation of my improved fire extinguisher. Fig. 2 is a vertical sectional view of the same. Fig. 3 is a fragmentaryview of my extinguisher showing how the chemicals are mixed when the same is inverted. Fig. 4: is a detail view of the valve closing means which I employ. Fig. 5 is a fragmentary view showing a casing in section having a modified form of receptacle and supporting means therefor. Fig. 6 is a cross sectional view taken on the line w-m, Fig. 5.

In the drawings 1 designates a casing suitably constructed of sheet metal or the like. The casing 1 is provided at its upper end with the screw threads 2. Formed within the casing 1 is the ofi" set portion 3 and secured to the side of the former is the bracket 4.- A glass tube 5 is adapted to engage said of? set portion and to be inserted through the bracket 4 whereby the same may be held in place. Pivoted to the casing 1 as shown at 6 is a valve 8, which has the packing material 7 secured thereto for a purpose that is obvious. Also secured to the extension of Serial No. 658,995.

the casing 1 is the handle 9 whereby the devlce may be carried from place to place.

The body portion of the top or cap is somewhat cone shaped as shown at 10, the

bottom portion of the same being internally screw threaded as at l'lwhereby the same can be screwed upon the casing 1. Said top or cap has exterior screw-threads'at 19. which are engaged by internalscrewthreads of a closure member or cap 13. I have shown a chain 14 connecting the cap 13 and the handle 9.

It will be readily seen that when an alkaline solution such as bicarbonate of'soda is inserted into the casing 1 and an acid solution such as commercial sulfuric acid held within the tube 5 and the device inverted, the valve 8 will swing upon its pivot point 6 thereby allowing the solution held within the tube 5 to be mixed with the solution held within the casing 1, whereby the carbon Specification of tetters Patent. Patented Dec, 29, 1314,

dioxid gas will be formed which is a well known chemical for extinguishing blazes.

In Figs. 5 and 6 a slightly modified form of the construction is illustrated and in this disclosure, a supporting bracket 15 is connected with the side of the case member at a point well upalong the inner wall thereof, and the retaining bracket 16 is secured. at a point above the bracket 15. A container or vial 17 of glass or other suitable material is preferably shaped in its body portion as is indicated in Fig. 6 to conform to the inner wall of the case and this container is rested upon the supporting bracket 15 to have the neck 18 thereof pass through the retaining bracket 16 and to thus be held against accidental displacement. A valve member 19 is pivoted to the casing as at 20 to have free swinging movement and this valve may be formed after the disclosure in Fig. 4 to have a packing layer upon the lower side thereof to be received against the mouth opening of the neck 18 of the container. The mounting, filling, and operation of this structure disclosed in Figs. 5 and 6 is substantially identical with the like step of the structure hereinbefore described and therefore recapitulation will not be here indulged in.

It is thought from the foregoing that the advantages and novel features of my invention will be appreciated,

I desire it to be understood that I may make slight changes in the construction and in the arrangement and combination of parts without departing from the spirit of my invention provided such changes fall Within the scope of the subjoined claims.

Having thus fully described my invention What I claim as neW and desire to secure by Letters Patent is 1. In a fire extinguisher, a casing having an outlet opening, a receptacle Within said casing mounted for discharge of its contents through said opening, and a closure member hinged interiorly from said casing to normally rest in a closed relation over the mouth of said receptacle and to automatically open upon tilting or inversion of the extinguisher.

2. In a fire extinguisher, a casing having an outlet opening, a receptacle to be received Within said casing and constructed to contain and hold a chemical, a closure member hingedly mounted interiorly of said casing from one Wall thereof, and means positioned adjacent the mounting of said closure member to receive and hold the receptacle in a position that the closure member is normally swung to a position to seat over and close the passage therefrom, and all of said parts so arranged that the closure member is automatlcally unseated by tllting of the extinguisher and the contents of the receptacle isdischarged into the main body portion of the casing and through the outlet opening therefrom.

3. In a fire extinguisher, a casing having a top provided With an outlet opening, supporting means mounted upon said casing, a liquid receptacle removably held at a predetermined point by said supporting means and positioned to have the discharge end thereof at a point above the main liquid level of the casing, and a closure member hingedly connected With the sides of said casing to swing to a position over the discharge opening of said liquid receptacle and form a closure therefor and to automatically open upon tilting or inversion of the extinguisher.
